On the anniversary of 9/11 two US embassies are attacked. One of your ambassadors is killed and his body dragged through the streets, and you are apologising because someone, somewhere, might have hurt muslim feelings?
The muslim world hates you. They see you as the enemy. Nothing you do will appease them. They will not rest until you are subjugated, dead, or convert to islam.
This is not your fault. For heaven’s sake, stop apologising.
